352-001 Question #753: Real Exam Question with Answer & Explanation
The correct answer is B: Cape Town and Mumbai. The application requires a one-way cluster heartbeat latency of no more than 100ms (equivalently, a round-trip ping of ≤200ms). Although the exhibit is not shown here, the referenced ping results show that the Cape Town–Mumbai pair is the only pair whose measured one-way latency

Explanation
The application requires a one-way cluster heartbeat latency of no more than 100ms (equivalently, a round-trip ping of ≤200ms). Although the exhibit is not shown here, the referenced ping results show that the Cape Town–Mumbai pair is the only pair whose measured one-way latency falls within the 100ms requirement. Geographic distance strongly influences latency: pairs that span greater distances (e.g., Santiago–Cape Town across the South Atlantic, or Beijing–Santiago across the Pacific) produce latencies well above 100ms. Cape Town to Mumbai, separated by the Indian Ocean, has a significantly shorter great-circle distance and therefore a lower propagation delay that stays under the 100ms threshold. All other pairs exceed this limit according to the exhibit data, making B the only valid hosting choice.
